SAFE-BOLTWORK.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed May 5, 1913. Serial No. 765,439.

T 0 all whom it may concern:

Be it known that I, CARL BARTELS, a citizen of the United States,residing at Hamilton, Butler county, Ohio, have invented certain new anduseful Improvements in Safe- Boltwork, of which the following is aspecification.

This invention pertaining to safe bolt work of round safe doors will bereadily understood from the following description taken in connectionwith the accompanying drawings in which 7 Figure 1 is a rear elevationof the backplate of a round safe door fitted with an embodiment of myimproved bolt work; Fi 2 a section thereof in the plane of line a ofFigs. 1 and 5; Fig. 3 a plan, on an en larged scale, of one of thebolt-throwing cranks; Fig. 4 a side elevation of one of thebolt-throwing cranks, the safety ring appearing in horizontal section inthe plane of line .7) of Figs. 1 and 3; Fig. 5, a plan of the initialone of the bolt-throwing cranks, part appearing in vertical section inthe plane of line 0 of Figs. 2 and 6; and Fig. 6, a side elevation ofthe initial bolt-throwing cranks, the safety ring appearing inhorizontal section in the plane of line (Z of Figs. 1 and 5.

In the drawings :l, indicates the back ofa round safe door, which backmay be the door itself or the back-plate not unusually provided upon theback of the door for carrying the bolt work; 2, a pair of ringsconcentrically carried by the back-member 1; 3, bolts adapted to slideradially through rings 2, there being as many of these bolts as desired,Fig. 1 illustrating three of the bolts complete, location for additionalbolts being indicated by dotted radial lines; l, a bearing-ring disposedagainst the rear face of the back-member, concentric with rings 2; 5,screws, securing the bearing-ring firmly to back-member 1; 6, a rabbetformed in the outer rear surface of the bearing-ring; 7, anactuating-ring fitted to turn freely in the rabbet of the bearing-ring;8, clip-ring lying to the rear of the bearing-ring and overlapping theactuating-ring; 9, screws passing through the clip-ring and anchoredinto the bearing-ring to hold the clip-ring in place, Fig. 2illustrating these screws as going into the heads of screws 5; 10,notches in the periphery of the actuating-ring, there being one notchfor each bolt; 11, a circumferential series of studs projectingrearwardly from the back-member around the actuating-ring; 12, a diskmounted to turn on each of studs 11, and overlying the actuating-ring;13, a crank-pin preferably proyided with an anti-friction sleeve,projectlng rearwardly from each crank-disk, these crank-pins engagingthe notches of actuatingring 7 1 1, a second crank-pin carried by eachof the crank-disks and projecting forwardly therefrom, the twocrank-pins of each disk being located at substantially ninety degreesfrom each other; 15, a shank projecting inwardly from each bolt, underits appropriate crank-disk; 16, a notch in each of these shanks, thesenotches engaging the appropriate crank-pins 1 1; 17, a toothedsegmentfast with one of the crank-disks 12; 18, a spindle mounted toturn in the back-member, its axis being disposed near to and parallelwith stud 11 carrying that one of the crank-disks which is provided withthe toothed segment; 19, a pinion fast on spindle 18 and engaging thetoothed segment; 20, a keeper-ring disposed concentric to rings 2 andengaging the circular series of studs 11; and 21, a crank-disk connectedwith that particular one of the crankdisks 12 which is actuated bytoothed segment 17, the pair of crank-disks formed by crank-disk 21 andits companion disk 12 straddling actuating-ring 7, the crank pin 13pertaining to these straddling crankdisks being connected to both disks.

If pinion 19 be turned, by any means whatever, it will cause the turningof the particular crank-disk which carries the toothed segment 1?, andthe crank-pin 13 of that crank-disk will cause the turning ofactuatingring 7. The turning of actuatingring 7 will obviously bringabout the turning of all of the rest of the crank-disks, and the turningof the crank-disks obviously brings about the endwise motion of thebolts, moving them outward for locking purposes and inwardly forunlocking purposes. The mounting of actuating ring 7, in thebearing-ring 4 leaves a large clear space upon the back of rear member1, on which may be mounted any locking mechanism usual in round-doorsafe construction, a condition not obtainable where the actuatingringtakes the form of a disk and turns upon a central pivot or stud.

The crank-disks are held in place by nuts upon the rear ends of thestuds. In the absence of keeper-ring 20 the nuts would hold thecrank-disks securely in place, but if in the course of time, one ofthese nuts became loose and displaced, a lockout might result. But inthe present construction, involving keeper-ring 20 the displacement of asingle nut or a number of nuts would not permit the damagingdisplacement of any crank-disk, indeed, it is obvious that the providingof nuts upon very few of studs 11 will be sufiicient to maintain thekeeper-ring in place and thus maintain the crank-disks in properposition.

lVhen actuating-ring 7 is turned it acts, as has been before explainedon the bolts, each crank-disk acting on one of the bolts. But theparticular crank-disk to which operating power is applied as by means ofthe pinion 19, has an extraordinary duty to perform in that power mustbe transmitted through it suflicient to actuate the entire series ofbolts. It is for this reason that the particular crank-disk in questionis reinforced by the second crank-disk 21, these two crank-disksstraddling actuating-ring 7.

I claim 1. Safe bolt work comprising, the backmember of a round safedoor, concentric bolt-rings carried at the rear thereof, bolts fitted toslide radially in said rings, a shank projecting inwardly from eachbolt, a crankpin notch in the side of each shank, a circularactuating-device mounted for rotatory movement on said back-memberinwardly of the ends of said shanks, notches in the periphery of thecircular actuatingdevice, means for turning the actuating-device, and acrank device for each of said bolts supported by said back-member andhaving each a crank-pin engaging the notch in the shank of a bolt and anotch in said actuating device, combined substantially as set forth.
